The following tests need to be performed in these modules: assign, book, choice, folder, forum, glossary, imscp, page, quiz, resource, scorm, survey and wiki. The site qa.moodle.net already has them in the Activity examples course, but you might have to add files in their content. IMPORTANT : Please make sure to include files in the content or in the description for each module. In the app, open the module. In the context menu you should see the time the module was modified or just " Download " if the time cannot be calculated (book, choice, glossary). Next to the time you should see the prefetch icon if the module hasn't been downloaded. Please notice that Book, IMSCP, Page and mini-site resources are automatically downloaded when opened. If the module hasn't been downloaded, download it now. Once downloaded, check that the download icon has disappeared from the context menu. Also, check that you see the size used by the module. Please notice that the size will only be shown if the module has at least 1 file in its content or description. Now click the context menu action to delete the content and confirm. Once deleted, check that the size isn't seen anymore and the module is now marked as not downloaded (you see the download icon).
